Introduction

Property signs can perform the same tasks as you can do through commands, but then automated. They require redstone power to function and ignore cart ownership, so if you only want it to target trains you own, combine it with a switcher sign checking for owners.

Syntax

[train]

property

speedlimit

1.5

Second line: property

Third line: the property name to change

Fourth line: the value to set the property to

Boolean Statements

Property 'playerenterexit' is controlled using the lever

Boolean properties like playerenter and slowdown can be set using a statement to evaluate true/false. This makes it much easier to toggle something on or off with redstone, or based on another property of the train.

Remote Control

Remote Control You can remotely set properties on trains. Say your train is called train01, then you use the following on the sign:

[train train01]

property

maxspeed

0.4

Properties

The following properties can be set using both [cart] and [train]:

Property	Value example	Meaning
addtag	tag1	Add a single tag
settag	taga	Set to a single tag
remtag	a	Remove a single tag
addticket	expresstrain	Add a ticket that can be used for this train
setticket	expresstrain	Set the train to only accept this ticket
remticket	expresstrain	Remove a ticket so it can no longer be used for this train
addowner	Maxxue	Add an owner to the train
setowner	Maxxue	Clear all owners and set to this owner
remowner	Maxxue	Remove a single owner from the train
destination	station2	Set the destination
mobenter	false	Set if mobs can enter
playerenter	true	Set if players can enter
playerexit	yes	Set if players can exit
playerenterexit playerexitenter	yes	Sets both playerenter and playerexit at the same time to the same value.
spawnitemdrops spawndrops killdrops	true	Sets whether carts drop items when destroyed. When disabled, also disables contents of chest/hopper minecarts dropping.
viewdistance	10	(Paper servers only!) Sets it so that passengers of the cart/train have a certain chunk/entity view distance. Can be used to reduce lag in busy areas of the world.

The following properties can only be set using [train]:

Property	Value example	Meaning
name setname rename	Intercity#A	Sets a new name on the train. The #-sign is replaced with a number 1 to infinity.
dname setdname displayname setdisplayname	Trainname	Sets the display name used with trigger signs (%triggernameN%)
exitoffset exitlocation exityaw exitpitch exitrotation	2/0/0 200/45/-2333 30 0 90	Change player exit offset, yaw, pitch and rotation. Exit location uses absolute coordinates, exit offset relative to the cart(s).
speedlimit maxspeed	0.6	The maximum allowed speed the train can go
pushing<ref name="collision">Old syntax for compatibility. Replaced by typecollision. See Collision modes</ref>	false	Set if the train pushes mobs, players, trains and misc
pushmobs<ref name="collision"/>	true	Set if the train pushes mobs
pushplayers<ref name="collision"/>	no	Set if the train pushes players
pushmisc<ref name="collision"/>	yes	Set if the train pushes misc (items, boats, etc.)
playercollision mobcollision traincollision misccollision	default cancel kill killnodrops push enter link	Set a collision mode for the train against players, mobs, trains or other types of entities.
slowdown	false	Set if the train slows down, either by gravity or by friction
slowfriction	false	Set if the train slows down due to friction
slowgravity	false	Set if the train slows down, or speeds up, due to gravity
gravity	1.0	Changes the acceleration and deceleration due to gravity (multiplier, 1.0 is default)
linking	deny	Set if the train can link with other trains
collision	allow	Set if the train can collide with other entities
keepcloaded loadchunks keeploaded	true	Set if the train keeps nearby chunks loaded
default setdefault	stat1def	Load one of the default train properties found in DefaultTrainProperties.yml into this train
banking	1 0	Change the banking (First number: Strength, Second number: Smoothness)
godmode invincible	true	Makes a train invincible, so that players cannot destroy it by hitting it. Players with the train.break.any permission (default: OP) can break trains anyway.
waitdistance waitdelay waitacceleration waitpredicted		See the Wait Property section
route add route set route remove route clear	destination_name	Adds/removes/clears/sets the destinations of the route set for a train. Destinations are added at the end.
route load loadroute	my_saved_route	Loads a previously saved route by name.

Set name

The name property alters the name of the train. To account for multiple trains being renamed, and because every train needs a unique name, the # value is added as a counter-based replacement. For example, the first train passing over the property sign with name value: Intercity#A would be named Intercity1A and the second Intercity2A, and so on. You can use this in combination with the spawner sign to spawn trains with a fixed naming system. This naming system can then be used for remote control to control all trains of a certain spawner or category.

Keep Chunks Loaded

Trains can keep chunks around them loaded like players do. This allows them to move through the world without unloading when there are no players nearby. This feature can be enabled per train using the keepchunksloaded or keeploaded property. This can be set with a legacy true/false value, or a load mode and radius.

On modern versions of Minecraft a chunk load type is also active, which can be full, redstone or minimal. Full will tick entities in the chunks loaded, redstone will not tick entities but will simulate redstone physics, and minimal will not run either. To improve server performance it can help to switch the mode to minimal with a lower radius when the train is driving long distances that don't require world simulation.

Value	Description
false	Disables the chunk loader. The train will now unload if no player is nearby.
true	Enables the chunk loader with a radius of 5x5 full entity-ticked chunks. In effect this loads a 9x9 area of chunks. Equivalent to full 2
minimal 0	Enables the chunk loader, but only loads the chunks the train is inside of. Does not simulate entities or redstone (except for the train itself). This has the most performance and is suitable for long-distance travel.
redstone 2	Enables the chunk loader, loading and simulating a 5x5 block-ticked (redstone simulated) chunks, and an outer 7x7 layer of non-simulated chunks. Useful at stations when redstone has to be simulated, but entities at these stations don't need to be ticked.
full 10	Enables the chunk loader, loading a 21x21 area of chunks and simulating entities inside. A 23x23 layer around it is block-ticked, and another 25x25 layer around that is not simulated. So this is actually loading 25x25 chunks. If you're looking for a chunk loader that acts like a Player, this is it.

Wait Property

The wait properties control when a train will automatically slow down. This can be used to slow a train down when obstacles are ahead of the train. This feature largely replaces the older waiter sign, and is a lot more intelligent:

• Maintain distance with other trains up ahead
• Slow down approaching occupied mutex zones
• Slow down approaching a blocker sign that will block the train

The following 'wait' properties exist:

Property	Example Value	Description
waitdistance	20.5	Distance to keep between this train and the train ahead, in blocks. The train will slow down or stop completely maintaining distance.
waitacceleration	20kmh/s	The rate of acceleration at which trains slow down or speed up when obstacles ahead appear or disappear. When specifying two numbers, the first number is the rate speeding up, the second number the rate slowing down. This can be set without the waitdistance, and will be used to slow down when approaching blockers or mutexes.
waitdelay	30	When the train is completely stopped due an obstacle, waits at least this delay in seconds until starting to move again
waitpredicted	false	Controls whether the path the train will take is predicted. By default on. When enabled, this will take into account switcher signs and where the train will be routed to when checking for obstacles.

They can also be configured with the /train wait <property> <value> set of commands.
